Description
Technical field
The utility model belongs to road quality check implement technical field, relates to a kind of high-speed road conditions detection vehicle of estimating multinomial road quality index that can be used for detecting.
Background technology
In the construction of high-grade highway, operation, maintenance, the multinomial index of quality situation of road such as the various environmental informations of surface evenness, construction depth, pavement track, road surfaces crack and road both sides index situations such as (as guardrail, side slope, center insulation strips) all are very important for construction department and traffic management system.How These parameters is carried out fast, objectively detected and estimates, be the problem that relevant department extremely pays close attention to for a long time always.
At present, this area is detected with the present situation of estimating as described below to relevant road quality index.
Detection and evaluation for surface evenness, construction depth index, though adopted advanced laser measuring technology so far, but its many independent detection and evaluations that also are only limited to these two indexs, and only be to detect roughness index on the wheel path, still do not accomplish to make it to carry out high efficiency simultaneously and detect with other pavement quality index.
For the detection and the evaluation of pavement track index, the laser detector existing questions that adopts mainly is that the laser probe quantity that installation is laid on cross-sectional direction is few at present, and detection width is less than the width of a moving traffic lane, and accuracy of detection is low; The crossbeam that laser probe is installed in addition often is laid in the outside of inspection vehicle, and the width of crossbeam also exceeds the width of inspection vehicle, is unfavorable for traffic safety.The detection of road pavement rut index also still detects separately generally speaking, does not also accomplish to make it to carry out high efficiency simultaneously with other pavement quality index and detects.
Detection and evaluation for damaged situations such as pavement cracks, the main at present mode that still adopts the visual record of artificial walking to detect, have problems such as detection efficiency personal safety hidden danger low, that influence normal traffic and testing staff is big, and the existing in recent years digital image method of inspection of using does not accomplish yet that carrying out high efficiency simultaneously with other pavement quality index detects.For the detection of road environment information, also mainly is at present to adopt artificial method to carry out in addition, efficient is low, can not realize that long distance detects on a large scale.
Even if at present the detecting device of the existing multiple tracks road index that adopts generally also only is the comprehensive of several single indexs, also do not realize the comprehensive detection of all indexs, so that its function and performance also all are difficult to is satisfactory.
